20 d massey problem with 3 point lift Pump.
ran tractor for years with no problem then got hung up and 3 point went out, after taking it apart found that 3 point lift pump cracked. replaced pump piston and ring.. pump blew apart again in 12 seconds.. took apart again cleaned everything changed all fluids again replaced 3 point lift pump, piston and rings again pump blew apart in about 15 seconds lift arms did not even get all the way up. you could hear the pump blow apart..is there a check valve or something that I cannot seem to locate nor does my manual refer too.. all other hydraulics are working fine including front bucket.
